Abstract (en)
[origin: WO2016093934A2] A functionalized polyolefin and a tire tread composition comprising the functionalized polyolefin is described. The functionalized polyolefin comprises a vinyl/vinylidene-terminated polyolefin in which the vinyl/vinylidene terminus is functionalized with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality. The invention is also directed to the synthesis of vinyl/vinylidene-terminated polyolefins, functionalization at the vinyl/vinylidene terminus with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality.
